GENERAL DESCRIPTION
The ADN2890 is a high gain, limiting amplifier optimized for
use in SONET, Gigabit Ethernet (GbE), and Fibre Channel
optical receivers that accept input levels of up to 2.0 V p-p
differential and have 3 mV p-p differential input sensitivity. The
ADN2890 provides the receiver functions of quantization and
loss of signal (LOS) detection. The ADN2890 can easily operate
at up to 3.2 Gb/s to support LX4 transceivers.
The limiting amplifier also measures average received power
based on a direct measurement of the photodiode current with
better than 1 dB of accuracy over the entire input range of the
receiver. This eliminates the need for external average Rx power
detection circuitry in SFF-8472 compliant optical transceivers.
The ADN2890 limiting amplifier operates from a single 3.3 V
supply, has low power dissipation, and is available in a space-
saving 3 mm × 3 mm 16-lead lead frame chip scale package
(LFCSP).
